Notes: The blue-green Stropharia mess…
These were rather small, 1-3 cm across, growing in grass, scant partial veil. and the cap faded to yellowish, losing most of the blue-green color. It seems to match S. caerulea (=S. pseudocyanea?) okay.
S. aeruginosa seems to be larger and have a more membranous veil and not fade as much…
Can anybody add anything???

for the distinctions guys, very helpful
as outlined by Breitenbach:
S. aeruginosa – fibrillose-membranous annulus when young, white floccose gill edges, abundant mostly clavate cheilocystidia, hyphal ends in ixocutis cylindrical.
S. caerulea (=cyanea)- fragmentary annulus even when young, concolorous gill edges, abundant rostrate cheilocystidia, hyphal ends in ixocutis clavate.
Both fade to yellow as they age. P. pseudocyanea is still legit as far as I know, having a significantly smaller stature. I would go with caerulea here judging by the veil and gill edges.
Stropharia caerulea has thin cystidia on a fertile gill edge, so the edges of the gills should go grey. S. aeruginosa has thick cystidia on a non-fertile edge, and the gill edges should be off-white. I found one of these on Sunday, so I have to back to books on this one myself soon here. Also I think S. aeruginosa tends to have a more persistent membranous veil. I think you can see this on my obs. from Europe:
But someone else can add to this, if I’ve just gotten this wrong…
the perfect cyanea to me. Soon disappearing ring, and soon fading cap colour, pale and somewhat reddish spores.
S. pseudocyanea is a smaller species, also quickly fading, but in general smooth-capped and more conical, and the gills have a white edge.
I don’t know if caerulea is a synonym or another species that belongs to Psilocybe..
These are beautiful! I’ve never seen this before.
